6 c_nnpnts - interpolate at a single point
7
9 void c_nnpnts(float, float, float *);
10
12 void c_nnpntinits (x, y, z);
13
15 x The X coordinate of the point where interpolation is
16 desired.
17
18 y The Y coordinate of the point where interpolation is
19 desired.
20
21 z *z is the interpolated functional value at the point (X,Y).
22
24 This function is invoked when you want to interpolate at an individal
25 point. c_nnpntinits must be called prior to calling c_nnpnts.
26 c_nnpntend must be called to terminate single point mode.
27
29 To use c_nnpnts, load the NCAR Graphics library ngmath.
